Class GlyfDescript

    • Field Detail

      • ON_CURVE

        public static final byte ON_CURVE
        if set, the point is on the curve.

        Constant Field Values
      • X_SHORT_VECTOR

        public static final byte X_SHORT_VECTOR
        if set, the x-coordinate is 1 byte long.

        Constant Field Values
      • Y_SHORT_VECTOR

        public static final byte Y_SHORT_VECTOR
        if set, the y-coordinate is 1 byte long.

        Constant Field Values
      • REPEAT

        public static final byte REPEAT
        if set, the next byte specifies the number of additional times this set of flags is to be repeated.

        Constant Field Values
      • X_DUAL

        public static final byte X_DUAL
        This flag as two meanings, depending on how the x-short vector flags is set. If the x-short vector is set, this bit describes the sign of the value, with 1 equaling positive and 0 positive. If the x-short vector is not set and this bit is also not set, the current x-coordinate is a signed 16-bit delta vector.

        Constant Field Values
      • Y_DUAL

        public static final byte Y_DUAL
        This flag as two meanings, depending on how the y-short vector flags is set. If the y-short vector is set, this bit describes the sign of the value, with 1 equaling positive and 0 positive. If the y-short vector is not set and this bit is also not set, the current y-coordinate is a signed 16-bit delta vector.
